The Molecular Microscope Era: How Nanotechnology, Liquid Biopsy and AI Are Reshaping Cancer Detection and Precision Medicine

Introduction: Strategic Context — From Visible Tumors to Molecular Signals For much of modern oncology, cancer detection has depended on identifying a tumor after it becomes visible through imaging, produces symptoms, or generates abnormalities that can be detected through conventional laboratory tests. Biopsy and histopathology remain essential for establishing many cancer diagnoses, but they often…
